Do not trust a neighbor; put no confidence in a friend. Even with the woman who lies in your embrace be careful of your words. (NIV)
Trust not in a neighbor; put no confidence in a friend. Keep the doors of your mouth from her who lies in your bosom. [Luke 12:51-53.] (AMP)
Trust ye not in a friend, put ye not confidence in a guide: keep the doors of thy mouth from her that lieth in thy bosom. (KJV)
